Because the differences between O(N), O(log(N)) and O(N ** 2)
operations are often relevant.

The latest Python version is systematically slower
than the previous ones as soon as one uses non ascii
strings.
Python users are discussing code optimizations without
realizing the tool they are using, has killed itself

No, it isn't. You've previously demonstrated a *microbenchmark* where
3.3 is slower than 3.2. This is a far cry from

I am not seeing a obvious way to do this without multiple for loops, but
maybe there is not :-)
In the end I am going to what to get triples, quads... also.
Thanks

@Emile,
I feel a little stupid, in my mind it was more difficult than in reality.
x = 'apple'
for f in range(len(x)-1):
print(x[f:f+2])

have a large set of strings to process. I'll try some timings if I get a

To All,
I appreciate the range of answers and the time each of you take to think
about and answer my question. Whether or not I use them I find them all
educational.
Thanks again.
